Its basically the same as having multiple versions of gnuradio
installed, especially considering that between major versions theres API
and ABI issues. So I would just recommend putting the installs in
different prefixes. I do this all the time for my benchmarking.
Here is one of the path scripts, I just run: source foo.sh
derp_prefix=/opt/usr/gr
export PKG_CONFIG_PATH=${derp_prefix}/lib/pkgconfig:${PKG_CONFIG_PATH}
export PATH=${derp_prefix}/bin:$PATH
export PYTHONPATH=${derp_prefix}/lib/python2.7/dist-packages:$PYTHONPATH
export GRC_BLOCKS_PATH=${derp_prefix}/share/gnuradio/grc/blocks
export LD_LIBRARY_PATH=${derp_prefix}/lib
